RESUMO
PURPOSE: To assess and compare uncorrected binocular distance visual impairment rates in U.S. Hispanic children and adolescents. METHODS: Data from the Hispanic Health and Nutrition Examination Survey, 1982-1984, were analyzed for 6-19 year-old Cuban-Americans (n = 317), Mexican-Americans (n = 2519), and Puerto Ricans (n = 988). Visual acuity was assessed using Sloan Letters or Landolt Rings. RESULTS: Prevalence rates of uncorrected binocular distance visual impairment (20/30 or worse) were 15.5%, 14.9%, and 23.6% for Cuban-Americans, Mexican-Americans, and Puerto Ricans, respectively. After adjusting for age and gender, the differences between Puerto Ricans and both Cuban-Americans and Mexican-Americans were significant (p < 0.05). Children 6-12 years of age had lower visual impairment rates than 13-19 year-old adolescents. Girls had higher age-adjusted visual impairment rates than boys; these gender differences were statistically significant among Mexican-Americans (OR = 1.6, 95% CI = 1.1, 2.2) and Puerto Ricans (OR = 1.7, 95% CI = 1.2, 2.4). CONCLUSIONS: Among Hispanics, Puerto Rican children and adolescents have the highest prevalence rate of uncorrected binocular distance visual impairment; older age and female gender are associated with higher rates of uncorrected visual impairment.

OBJECTIVES: The purpose of this study was to perform comparative analyses of the population-based prevalence of usual-corrected binocular distance visual acuity impairment among Hispanics and non-Hispanics in the United States. METHODS: Data from the Hispanic Health and Nutrition Examination Survey (HHANES), 1982-1984, and the National Health and Nutrition Examination Augmentation Survey I (NHANES I-A), 1974-1975, were analyzed to investigate the epidemiology of usual-corrected binocular distance acuity in adults 25 to 74 years of age among Cuban-Americans (N=396), Mexican-Americans (N=1,381), Puerto Ricans (N=513), African-Americans (N=250), and non-Hispanic white Americans (N=2, 660). Binocular distance acuity was assessed using Sloan Letters or Landolt Rings with the participants wearing their corrective lenses, if any. RESULTS: Prevalences of 20/50 or worse usual-corrected binocular distance acuity were 3.5%, 4.6%, and 6.6% for Cuban-Americans, Mexican-Americans, and Puerto Ricans, respectively, in the HHANES; and 7.7% and 4.1% for African-Americans and non-Hispanic whites, respectively, in the NHANES I-A. Within the HHANES, after adjustment for gender and age, Puerto Rican adults were found to have a significantly higher prevalence of visual impairment (20/50 or worse) and were significantly less likely to become unimpaired with usual correction than Cuban-American adults. Within the NHANES I-A, African-Americans were found to have a higher prevalence of visual impairment (20/50 or worse) and were significantly less likely to become unimpaired with usual correction than non-Hispanic whites. Higher prevalences of visual impairment (20/50 or worse) were associated with increasing age for all ethnic groups. After controlling for age, odds of usual-corrected visual impairment (20/50 or worse) were significantly higher in women than in men for Cuban-Americans and Mexican-Americans (odds ratios: 4.5 and 2.6, respectively). CONCLUSIONS: The results from this study suggest that compared to other Hispanic groups and non-Hispanic whites, Puerto Rican and African-American adults may not be receiving similar eye care services and/or may have more severe eye diseases.
